    摘要: Various embodiments provide a handheld surgical instrument including a laser source configured to emit a laser beam for generating a laser marker on a surface, an inertial measurement unit configured to detect a motion of the handheld surgical instrument and generate a first signal including information on the motion of the handheld surgical instrument detected by the inertial measurement unit, and a movable platform for holding a controlled tool tip. The handheld surgical instrument additionally includes an actuator mechanically coupled to the movable platform, and a processing circuit configured to control the actuator to move the movable platform based on the first signal generated by the inertial measurement unit and a second signal generated by a vision unit based on a movement of the laser marker, so that the movement of the movable platform at least partially compensates a tremulous motion of the handheld surgical instrument.

    摘要: The power system may include a main circuit arrangement having a power source, a load and a circuit breaker. The power system may additionally include an energy harvesting circuit arrangement connected to the main circuit arrangement. The energy harvesting circuit arrangement may include an operating switch and an energy harvester. The power system may also further include a trigger mechanism, which may be configured to, when detecting a current above a predetermined value in the main circuit arrangement, trigger the circuit breaker to switch from a closed mode to an open mode. The trigger mechanism may also be configured to trigger the operating switch to switch from an open mode to a closed mode for a predetermined duration, and back to the open mode after the predetermined duration, thereby storing electrical energy in the energy harvester.
